    摘要： A washpipe free feature may include a housing defining a chamber having a bypass portion and a securing portion. The housing has first and second bores to put the bypass portion in fluid communication with an annulus of a wellbore and a central bore of a downhole tubular, respectively. Further, the washpipe free feature includes a magnet secured in the bypass portion, a ferromagnetic ball disposed within the bypass portion, and a piston disposed within the chamber. A distal end of the piston blocks the ball from contacting the magnet in a run-in position such that the ball may plug the first bore in response to fluid flow from the tubular toward the annulus. Additionally, the piston is slideable to an open position such that the magnet may hold the ball out of a flow path between the first bore and the second bore in the bypass portion.

    摘要： A valve for downhole chemical injection control, having a single chemical injection fluid line (2) to feed all the injection points, regardless of the number of zones, exclusively electrically-driven by a single electric cable (3), with embedded sensing electronics (7), which communicate and activate an electric motor (4), coupled to a multi-position sphere (5) for dosing the chemical injection fluid, which, according to the electric motor rotation, is moved, altering its position, to enable the passage of interest to be selected, according to the volume of chemical fluid to be injected, a single turn of the sphere being required to commute all the possible positions, the performance of which is low in power consumption, and for a short period of time, having after its positioning in the desired passage zero consumption to maintain this position.

    摘要： A surge flow mitigation tool can include a surge flow valve that permits one-way fluid flow through a flow passage, and a bypass flow path that opens when a differential pressure across the surge flow valve is greater than a predetermined level. A method of mitigating surge flow in a well can include producing fluid through a tubular string with a bottom hole assembly including a surge flow mitigation tool connected downhole of a packer, the surge flow mitigation tool including a surge flow valve that permits the fluid to flow toward surface via the tubular string, but prevents the fluid from flowing into the well via the tubular string, and increasing a differential pressure across the surge flow valve to greater than a predetermined level, thereby opening a bypass flow path that permits injection flow from the tubular string into the well downhole of the packer.

    摘要： An object carrier including a housing having a bore with a diametrically larger portion and a diametrically smaller portion, an object keeper having a first and a second end, the first end being initially disposed in the diametrically smaller portion, an actuator assembly configured to move the first end of the object keeper from the diametrically smaller portion to the diametrically larger portion responsive to selected application of pressure, and an object disposed within the object keeper and secured within the object keeper while the first end of the object keeper is in the diametrically smaller portion, the object being released from the object keeper upon the first end of the object keeper moving to the diametrically larger portion. A method for managing an object-based operation downhole of a restriction including pressuring up on the object carrier, withdrawing the first end from the diametrically smaller portion, and releasing the object.

    摘要： A completion string includes at least one isolation packer positioned between well zones of a plurality of well zones, and a sand control assembly and a circulating assembly each disposed uphole of a washdown shoe in the bottom-most well zone. A top well zone includes a return valve assembly, a production packer, and a second circulating assembly and a second sand control assembly downhole of the production packer. The completion string also includes an outer string spanning from the bottom-most well zone to the top well zone, and an inner production string concentrically arranged within the outer string, creating an inner-annulus between the outer string and inner production string. The inner-annulus is continuous from the washdown shoe to the return valve assembly, and the inner production string includes a production valve disposed between the sand control assembly and the circulating assembly in each of the bottom-most and top well zones.
